Sierra Metals Acknowledges Press Release from Alpayana Announcing its Intention to Commence an Unsolicited Takeover Bid

Sierra Metals Inc. (TSX: SMT | OTCQX: SMTSF | BVL: SMT) (“Sierra Metals” or the “Company”) acknowledges the press release issued yesterday on behalf of Alpayana S.A.C. (“Alpayana”) announcing an intention to commence an unsolicited all-cash takeover bid to acquire all of the issued and outstanding common shares of Sierra Metals. Sierra Metals cautions shareholders that the announcement does not constitute an offer to acquire securities. Sierra Metals notes that there can be no assurance that any offer will ultimately be made, or on what conditions such an offer might be made.

At this time, the Board of Directors (“Board”) of Sierra Metals has not received any formal written offer from Alpayana. In fact, Sierra Metals has not received any recent indication of interest from Alpayana in respect of a proposed acquisition of the Company.

Sierra Metals continues to be committed to its long-term strategy of ensuring the Company delivers superior long-term value to all its shareholders and stakeholders.

The Board has formed a Special Committee of independent directors to advise the Board in relation to the Alpayana announcement. The Special Committee and Board note, as a preliminary matter, that the price of C$0.85 per share indicated in Alpayana’s press release is a very low 10.4% premium, appearing to be highly opportunistic in light of Sierra Metal’s high quality asset base and future growth plans.

The Company advises shareholders to take NO action at this time and will continue to provide appropriate disclosure of any material developments as they arise.
